In addition, using RT-PCR to detect expression of centrin homogene during Urechis unicinctus spermatid deferentiation and early embryonic development. The result revealed that (1) expression of HsCEN1 homogene is present during spermatid defferentiation including spermtid and sperm, but not in adult tissues including body wall tissue,intestinal mucous memberane cells and cell in coelom succus;(2) expression of HsCEN1 homogene is not present in unfertilized oocytes but present in that of released polar bodies after fertilization and parthenogenesis oocytes treated with A23187;(3) expression of HsCEN1 homogene is present during early embryonic development including two-cell stage,multicell stage,gastrula to trochophora.

我们还用RT-PCR方法检测了Centrin同源基因在单环刺螠精子分化过程和早期胚胎发育过程的表达，结果显示：在单环刺螠精子发生过程中的精细胞、精子团、精子中都有表达，而在成体的体壁组织、消化道组织、体腔球中则没有表达；在未受精卵中没有表达，而在受精后释放极体的受精卵和经A23187孤雌激活的卵中则有表达；在单环刺螠的早期发育过程——二细胞胚胎、多细胞胚胎、原肠胚、早期担轮幼虫——中都有表达。

So before applying Mather's theorem of connecting orbits to concrete Hamiltonian system, we have to check whether the set W〓 is empty or not, and which cohomology classes are C-equivalent. In present paper, by investigating the topological structure of action minimizing sets near a co-dimensional one torus which is preserved under generic perturbations and becomes hyperbolic in nearly integrable Hamiltonian system.

与传统的Poincaré-Melnikov方法相比，我们方法明显优越之处在于，一方面我们的方法不仅可以得到双曲环面之间的异宿轨道，而且当该环面附近的其它环面破裂时，可以得到不同Mather集之间的连接轨道，另一方面，我们把异宿轨的存在性的证明转化为双曲环面极小同宿轨的某种弱孤立性的证明，所需条件比Poincaré-Melnikov方法弱得多。

In 1984, South Africa made the law of regulating South Africa small and medium-sized enterprises behavior-South Africa Close Corporation Act.

而随着中国和南非关系的进一步发展，越来越多的中国人到南非创办中小型企业，目前在国内研究南非封闭公司法这一极具特色的中小企业法律制度尚属空白，因此，对南非封闭公司法律制度的研究有着现实的意义。

There are also other Word, wps2000, and so some word processing software, in theory, you can also generate the ps file, and can output film, but in fact the prepress output is to be carried out such as imposition, registration syndiospecific, crop marks, and so some processing, and the word, wps2000, and so the software can be said in this respect is powerless to do anything, especially once the color is doing well, and then go to the late processing will be output to the pre-press staff bring great difficulties.

其它还有一些像word、wps2000等一些字办理软件，假想上同样可以天生ps文件，并且可以输入胶卷，但本质上印后输入都给举行诸如拆版、加套准规线、裁切线等一些办理，而word、wps2000等软件在这方面可以说是多才为辛，出格是不暗白稿，一旦做好后，再去后期加工，不兵会给印后输入处事职员带来极不小的艰难。

And the cross correlation function is approximately zero, which makes them suppress the disturbances due to the other users. After describing some basic knowledge of chaotic theory in chapter 2, we interview and classify the applications of chaos in communications including chaos secure communication, chaotic spreading codes for multi-user access in spreading spectrum system and chaotic modulation and demodulation in chapter 3. FM-DCSK system with non-coherent demodulation offers the best performance in chaotic modulation schemes.

在混沌调制方案中， FM-DCSK调制是一种极具竞争力的混沌调制方式，它克服了CSK、COOK、DCSK解调中存在的估计问题的缺点，在无线信道的传输过程中，可以很好的抑制噪声干扰与多径衰落，并且能获得非常优越的解调性能，加上混沌信号本身优越的保密性能，该调制方式在未来的无线通信领域存在着巨大的潜在优势。

It is reported that the fifth-generation energy-saving Rongsheng star refrigerator, use of VIP vacuum insulation panels, ultra-efficient green fluorine-free compressor, double F-type high-performance wire-tube evaporator, and more energy-efficient dual airbag door closed, a new generation of cyclopentane composite foam technology and other energy-saving Multi-leading technology to ensure excellent insulation refrigerator insulation performance, power consumption of only 0.25 days, the volume for the same paragraph of ordinary refrigerator 1 / 3, is currently on the market to buy the lowest power consumption refrigerator, can be called "energy champion."

据介绍，容声第五代节能明星冰箱，采用了VIP真空隔热板、超高效环保无氟压缩机、双层F型高效丝管式蒸发器、多气囊节能双门封、新一代环戊烷复合发泡技术等多重领先的节能技术，保证冰箱极佳的绝热保温性能，日耗电量仅0.25度，为同容积段普通冰箱的1/3，是目前市场上能购买到的耗电量最低的冰箱，堪称"节能冠军"。
